An "anchor" is a heavy object, typically made of metal, used to secure a boat or ship to the sea floor. It prevents the vessel from drifting due to wind or currents, ensuring it stays in a specific location. Anchors come in various shapes and sizes, designed for different types of boats and water conditions. In a broader context, the term "anchor" can also refer to something that provides stability or support. For example, in broadcasting, an anchor is a person who presents news and information on television or radio, helping to guide the audience through the program.
